Heltec Wireless Paper 1.1 stuck "LORA MODE 0"

#1

I bought a Realtek Wireless Paper, and everything works perfectly, except for the display. It shows “LORA MODE 0” and “HF” on the screen and won’t change.

I’ve tried several tutorials, but nothing has worked so far.

Any ideas?

You will need some appropriate e-ink drivers to refresh the display. The factory examples from Heltec for the Wireless Paper v1.1 should help you, or otherwise this great driver from Todd. Note that there now is a newer version labelled v1.1.1 or v1.2 that uses a different display. But examples for v1.1 should work.

Thanks for the tips, BNS.

I tried the drivers I got from Heltec, but none of them worked. I’ll give Todd’s a shot and see if I have better luck.

The display is showing text, so I believe it’s not broken or suffering from a loose connection.
